Daniel Kirkwood (September 27, 1814 - June 11, 1895) was an American astronomer. His most significant contribution was his study in the orbits of the asteroids. In 1866 he published the discovery of gaps in the distances of asteroids from the sun, named Kirkwood gaps in his honor. He also was the first to suggest that meteor showers are debris from comets.
